There has been small infantry groups leaking into the city for months. They tend to make it in (sometimes in civilian clothes), cause problems if they can, and die. Similar case as Kupiansk.
It is hard to qualify these as much more than vast grey zones because there is no well regulated "line" between forces defined in much of these areas due to no armor, marginal men, a surplus of drones, and the "transient" nature of troop concentrations that follow.
